You can also turn them to slide only, meaning when you scroll the side of the screen where they normally are displayed they pop-up there. All of it in the UI menu.
Two questions in regards to the awesome historical battles: 1. Is the terrain for the Battles handcrafted to suit the location of the battle and 2. Could you guys give your sources at the end of the description of each battle or would that be too much ? Id love to know where to get more information about them.
